Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731422, here are decompositions:

5 + 8731417 = 8731422
41 + 8731381 = 8731422
53 + 8731369 = 8731422
59 + 8731363 = 8731422
79 + 8731343 = 8731422
83 + 8731339 = 8731422
101 + 8731321 = 8731422
109 + 8731313 = 8731422

Showing the first eight; more decompositions exist.
